I would like to point $NIX_PATH to ~/.nix-defexpr/channels instead of ~/.nix-defexpr/channels_root as currently. I don't want to have to type that every time I run nix-env. What's the right way of doing that?

I would simply define the variable the way you want it in your ~/.profile.

  • What statelessness? You update channels "imperatively" - that's how they're designed, so that by default you install from the latest-updated channel without having to specify e.g. the exact commit hash.

    Yes, but we try to keep the state in /etc/nixos/configuration.nix and not all over the place like in a regular Linux distro. I am hoping to have a tidy solution with which I can make a reproducible recipe. I may be using that to create cloud instances, or sharing configuration with colleagues.

I still want to know how to do it via configuration, but imperatively through an expression written in a file I can do



$ nix-env -if /this/file.nix -I ~/.nix-defexpr/channels


This way I'll be using the user's channels. Without it ~/.nix-defexpr/channels_root is read instead. Which is what I'm trying to avoid here.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
